Project Red Mod 1.12 mainly adds Project Red are Wires and Logic Gates. Wires work sort of like redstone dust, except they can be transmitted for up to 256 blocks, and go up and under blocks as well as around corners. Logic gates allow you to fit what would otherwise take a huge building of redstone craziness and squeeze it into a tiny logic gate, that can be placed on any solid block on any side. This mod gives you the tools you need to push redstone to its true potential.
